Intel HD Graphics Ironlake driver issue

[cocobean]

Usually blacks out screen before Haiku logo boot splash screen appears or before the desktop appears. Normally, desktop screen won't appear unless we use the fail-safe (VESA) graphics driver.

WORKAROUND: Unplug monitor during bootup and reattach after computer fully boots to installer/desktop.

NOTE: Can change screen resolutions under preflet up to 1920x1440 under VESA driver (mentioned in preflet)

Seems like the intel_extreme driver grabs the monitor's EDID and IGP VBIOS info - so I see two sets of display resolutions tables:

VBIOS max res: 1920x1440 
monitor max res: 1280x1024@75hz
Intel VGA output->VGA: works

Then, either I can get past the Haiku boot splash screen and it fails to a black screen, or it just fails directly after I use the Haiku boot loader menu. Sometimes, I don't get the Haiku logo splash screen at all until it fails to black screen.

With effort, I can get it to load with the VESA driver in which I can modify screen resolutions up to 1920x1440 (I also see this in the boot menu for modifying default screen mode settings).

NOTE: Setting fail-safe driver (true) and using 1024x768x32 @60hz default. Rebooted. This works as a workaround. Screen preflet shows monitor info, monitor dpi, and VESA driver (VESA) in left window pane. Resolutions changeable (when applied) from 640x480 to 1920x1400.

Now that the output works reliably through the Intel video VGA output, we can isolate the intel_extreme driver issues better.

NOTE: Modeline PLL clock info seems off. See working modeline xrandr output for comparison.

KERN: intel_extreme: compute_dpll_g4x: best MHz: 109 (error: 0.116997)

Haiku VESA driver screen preflet info - hrev53365 x86_64

[cocobean]

Tested hrev53556 x86_gcc2.

1. Fail point right after:

   Intel extreme: Found EDID information!!
   (Detailed monitor info appears)
   Post-install script: sshd_keymaker.sh
   Size: 36 cm x 29 cm
   

2. Then, display screen inits to black screen. Fails at point normally where Haiku logo splash screen would appear.

NOTE: I didn't get the crtc info. Also, I get the 'h:' info, but not the 'v:' info after the clock info. Normally, I get the 'h:', 'v:', Maximum pixel clock info, H/V Freq ranges, and crtc info. Also, the full serial number of the active monitor (last four digits appear here).

If the intel_extreme driver can mimic/baseline the VESA driver moreso, this may/should solve the problem as the VESA driver works as expected with this graphics chip.

Please include an updated syslog booting with the driver enabled.

[cocobean]

LiveCD session: I only have recorded video session and screenshots from the online syslog debugger.

[cocobean]

You can close this ticket. I remember seeing that this driver was not intended for the Intel HD series. Possible quick fix is to default all Intel HD graphic chips (Gen 5 and higher) to the VESA driver (i.e. removing them from the intel_extreme driver).

[pulkomandy]

Then let's not close the ticket until that is done.

[cocobean]

Tested hrev53790 x86_64; Default settings: No Haiku splash screen, black screen output. Set the default resolution to: 800x600x32 Got the Haiku boot screen. Rocket lit up. Monitor resets. RESULT: Black screen.

If monitor disconnected before bootup, wait 3-5 minutes for full bootup, reconnected monitor. Got blue desktop (success!). So, seems like a sync issue during boot to desktop.

Intel driver seems to work fine other than the monitor sync issue during boot to desktop.

[vidrep]

The "trick" cocobean outlines above works indeed. I've tried it on 3 PC's so far.

Attached is a screenshot of the Intel driver working at full HD resolution.

[pulkomandy]

The "trick" makes the driver go "oh, there's no display so I will not set up anything". So it's essentially the same as using the VESA driver.

As I mentionned in my forum post and already here in the comments, the intel driver does not work at all for these newer devices currently. Up to sandybridge it's ok, but the later ones we're missing support in the driver.

Syslog for intel_extreme driver- Ironlake test, hrev53790 x86_64

[cocobean]

Hmmm. With Live CD, I turned off monitor, booted CD, let things boot to installer screen, turned on monitor, selected 'Boot to Desktop', screen flashes/init, then it displays the desktop without monitor issues. I'm OK with this for now - versus the safe-mode driver setting or boot menu fiddling.

I'll await further...

[cocobean]

NOTE: Ironlake (Gen5) is BEFORE Sandy Bridge (Gen6). So, it is supported (based on driver info).

[pulkomandy]

Yes, but I don't have an Iron Lake machine here. So I probably missed some things.

SandyBridge and G45 are the ones I can test easily. For the other ones I need to carefully check the registers in the docs.

[ttcoder]

/me guesses he might need to keep an eye on this ticket, for an IronLake/Mobile (instead of IronLake/Desktop as in cocobean's screenshot) laptop that works well in R1/b1 but will get updated to b2.

Syslog for intel_extreme driver- Intel Ironlake GPU test, hrev53864 x86_64

[cocobean]

If I go into Haiku Boot Loader and set the video mode resolution to 1024x768x32, I can get the Haiku splash screen after I continue booting. The screen inits after the rocket icon lights up. Then, stays on a black screen - but finishes booting.

As long as I disconnect the monitor before Haiku splash screen disappears (i.e. after the rocket lights up), I can get a working desktop display. Works good enough for me at the moment.

NOTE: hrev53864 x86_64.

[pulkomandy]

If I understand correctly there are two problems here:

Problem 1: the splash screen (with boot logo and loading icons) does not work properly. This would be a problem in the VESA side because at that point the intel driver is not used

Problem 2: the desktop is also not working, this time with the intel driver

Is this correct?

I think it would be simpler, if possible, to first fix the first issue. Because if even the VESA BIOS provided with your card does not manage to set up a working display, it is unlikely that our own driver will.

[cocobean]

Fail safe VESA driver is not the problem. That works fine when enabled. Haiku splash screen usually comes up properly.

So, it is the intel_extreme driver.

If I don't touch anything and just let the computer reboot/boot up:

I see the intel_extreme driver reads the monitor's EDID info (i.e. monitor screen resolutions and product info) then the screen goes black from that point. If I disable the monitor, reboot, wait till disk activity finishes, then reconnect - I have a 1024x768 @ 60Hz display with the installer GUI options and I can either install or go to the desktop. Notice it looks like 'Screen' preflet shows the Intel driver info but not the correct monitor info since I disconnected the monitor.

So, it gets the monitor's EDID info, if connected, then ...

[pulkomandy]

I'm checking the attached syslogs and:

• They include only logs from intel_extreme, but sometimes other logs are important too. For example, the EDID info is dumped, as well as some info from the VESA driver, which can be relevant.
• They are all, as far as I can tell, from when you boot with the display unplugged (that is your workaround which is working fine).

To see where things go wrong I'd instead need a syslog from a failed boot, to try to understand what we try and fail to configure, and preferably a complete one.

Note that with the workaround, the Intel driver will not attempt to do anything, it will just leave the video card as configured using VESA to show the splash screen. So there is no real benefit to using the driver in that case.

• Continue boot

Result:

• Haiku splash logo appears. Lights up all small icons and disappears.
• Black screen (no install GUI or blue desktop screen)
